Patent DE-3238179-A1 (DE)
Title: System for measuring the concentration of a gas
Inventor: HEINISCH RUDOLF DR ING
IPC: G01N21/3504
Filed: 1982-10-15
Abstract: The application relates to a system for continuously measuring the concentration of a multiatomic, nonelemental gas using a nondispersive infrared single-beam photometer. The alternating light beam originating from a switched radiation source passes through an absorption cell with the gas to be measured flowing through it and simultaneously strikes two photoreceivers. One of the photoreceivers has a filter in front of it. The ratio is taken of the rectified output signals from the two photoreceivers and, since this is a measure of the concentration of the gas, it is fed to a measured-value indicator.

Title: Safety door lock for right-hand and left-hand use
Inventor: ZADOR JOSEF
IPC: E05B63/04
Filed: 1982-12-14
Abstract: Known door locks are designed with latches and bolts arranged symmetrically relative to the mid-plane of the lock and displaceable independently of one another, thus ensuring a space-saving form of construction. The bolt is designed either as a central bolt, that is to say extending between latch projections, or as a forked bolt, that is to say surrounding the latch in a fork-like manner. But at the same time, the bolts cannot be strong enough to guarantee sufficient protection against a mechanical break-in. To increase the resistance values of the bolt, therefore, the latch and bolt are each made one-part, with the result that these parts and particularly the bolt can be made large. The bolt and latch are installed asymmetrically relative to the mid-plane of the lock, but nevertheless once again form as a whole a unit symmetrical relative to the mid-plane of the lock, for which purpose the disengagement shank of the bolt has a one-sided extension forming the bolt and engaging under the latch, so that, despite the one-part form of construction of the latch and bolt, a compact constructional unit is obtained without any variation in the predetermined outer dimensions.

Filed: 1983-03-12
Abstract: LOW-PRESSURE CHAMBERS for improvment of all circulation processes in the human body. Chambers made to correspond to specific body parts of a rigid, transparent material, that is to say for the head, arms, legs, back and front of the body. Hitherto, there have only been available cup-like suckers for medical use, each one of these suckers only being capable of covering a fraction of the human body and the mode of operation being troublesome. The advantages achieved with the invention consist, in particular, in that it is for the first time possible to treat whole parts of the body uniformly, deliberately and in a controlled manner in order to improve all circulation processes in the human body.
Patent DE-3308983-A1 (DE)
Title: Circuit arrangement for the DC voltage supply of a digital telephone station
Inventor: PETRY SIGMAR DIPL ING
IPC: H04M19/08
Filed: 1983-03-14
Abstract: The invention relates to a circuit arrangement for the DC voltage supply of a digital telephone station fed via the subscriber line. At its input, the circuit arrangement has a rectifier bridge to prevent polarity reversal, a voltage limiter connected downstream which is controlled by the applied remote feed and, on its output side, a positive and a negative voltage tap which are in each case connected to earth via a capacitor. If the remote feed is activated, these two capacitors are charged up, which may produce a current which is so strong that the central unit detects a short circuit and de-activates the feed voltage. The object of the invention is to prevent this. The object is achieved by inserting a capacitor into the control circuit of the voltage limiter, which capacitor must first charge up when the remote feed is activated, and thus slowly opens the voltage limiter, which is closed in the rest state. The subject-matter of the invention can be used in all remotely fed digital telephone stations.

Patent DE-3347366-A1 (DE)
Title: Building block
Inventor: ZAUNER RAIMUND
IPC: E04B2/02
Filed: 1983-12-29
Abstract: The building block comprises a solid body with a system of narrow slits arranged therein. However, the provision of parallel slits adversely affects the transverse tensile strength of the building block body. Therefore, it is intended to create in the building block body a system of slits which both ensures good hardening of a solid block body produced by extrusion or in a formwork mould and does not adversely affect the transverse tensile strength of the block body. The slits are in this case profiled in cross form and distributed over the block body in a reticular manner, producing the advantage that zones (webs) of increased strength are formed in a criss-crossing manner between the slits and ensure a high load-bearing strength of the block body.

Title: Floor and wall construction
Inventor: STEPPLER KLAUS DIPL ING
IPC: F24D5/10
Filed: 1984-02-08
Abstract: The invention relates to a floor or wall construction which can be heated by hot air, in which a cavity through which the hot air can flow is bounded towards the room by a heat-conducting layer and to the other side by a heat-insulating layer and in which spacers are provided between the two layers. To make it possible to build in such a construction even in the cases in which the costs of building or of building alterations (building reconstruction) are under strong price pressure, the invention proposes that the heat insulation and the spacers constructed as supports are constituted by a single moulding, preferably of a hard plastics foam, the floor being built up of these mouldings.

Title: Process for producing hollow silicone mouldings and a silicone moulding produced thereby
Inventor: DERKMANN KLAUS DR
IPC: B29C33/52
Filed: 1984-03-21
Abstract: A process for producing hollow silicone mouldings is characterised in that, in at least one first casting operation, at least viscous silicone is poured into a flat negative mould which is open at the top and has a hollow space base corresponding to one half of the surface of the moulding, in that mould cores, in particular made of Styropor (expanded polystyrene), are arranged on the poured-in hot silicone layer in a way corresponding to the hollow space or to the hollow spaces to be formed of the moulding and casting-resistant pipe connections laid from the hollow spaces transversely to outside the negative mould are arranged and subsequently, in at least one second casting operation, the negative mould is completely filled with at least viscous silicone, whereupon, after joining of the first and second cast silicone layers and after releasing the cooled moulding from the negative mould, a solvent, in particular acetone, is conducted through the laid pipe connections to the mould cores in order to dissolve them and rinse them out of the interior of the moulding to form a hollow space. A silicone moulding produced according to this process is suitable in particular as a so-called temperature-control cushion through which temperature-controlled (heated or cooled) water can be passed at constant temperature.

Title: Masking plate for transferring a plurality of different structure planes onto a substrate
Inventor: HERWIG RALF E DIPL-PHYS
IPC: G03F1/00
Filed: 1984-07-20
Abstract: The invention describes a process for the cost-effective structuring of the prototypes of chips having microelectronic circuits by a photolithographic masking plate. The cost saving is achieved in that only one masking plate has to be made for all the planes of the circuit (preferably eight planes). By virtue of a special arrangement of the masking plate and the substrate and of the chip structures on the masking plate it is possible to ensure that the chip yield does not decrease to the same extent that the number of planes combined on the masking plate increases.
